Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023128, here are decompositions:

61 + 1023067 = 1023128
109 + 1023019 = 1023128
151 + 1022977 = 1023128
199 + 1022929 = 1023128
229 + 1022899 = 1023128
307 + 1022821 = 1023128
331 + 1022797 = 1023128
367 + 1022761 = 1023128

Showing the first eight; more decompositions exist.
